DETAILED DESCRIPTION Terms

The following is a glossary of terms used in this disclosure:

Memory Medium—Any of various types of non-transitory memory devices orstorage devices. The term “memory medium” is intended to include aninstallation medium, e.g., a CD-ROM, floppy disks, or tape device; acomputer system memory or random access memory such as DRAM, DDR RAM,SRAM, EDO RAM, Rambus RAM, etc.; a non-volatile memory such as a Flash,magnetic media, e.g., a hard drive, or optical storage; registers, orother similar types of memory elements, etc. The memory medium mayinclude other types of non-transitory memory as well or combinationsthereof. In addition, the memory medium may be located in a firstcomputer system in which the programs are executed, or may be located ina second different computer system which connects to the first computersystem over a network, such as the Internet. In the latter instance, thesecond computer system may provide program instructions to the firstcomputer for execution. The term “memory medium” may include two or morememory mediums which may reside in different locations, e.g., indifferent computer systems that are connected over a network. The memorymedium may store program instructions (e.g., embodied as computerprograms) that may be executed by one or more processors.

Carrier Medium—a memory medium as described above, as well as a physicaltransmission medium, such as a bus, network, and/or other physicaltransmission medium that conveys signals such as electrical,electromagnetic, or digital signals.

Programmable Hardware Element—includes various hardware devicescomprising multiple programmable function blocks connected via aprogrammable interconnect. Examples include FPGAs (Field ProgrammableGate Arrays), PLDs (Programmable Logic Devices), FPOAs (FieldProgrammable Object Arrays), and CPLDs (Complex PLDs). The programmablefunction blocks may range from fine grained (combinatorial logic or lookup tables) to coarse grained (arithmetic logic units or processorcores). A programmable hardware element may also be referred to as“reconfigurable logic”.

Computer System—any of various types of computing or processing systems,including a personal computer system (PC), mainframe computer system,workstation, network appliance, Internet appliance, personal digitalassistant (PDA), television system, grid computing system, or otherdevice or combinations of devices. In general, the term “computersystem” can be broadly defined to encompass any device (or combinationof devices) having at least one processor that executes instructionsfrom a memory medium.

User Equipment (UE) (or “UE Device”)—any of various types of computersystems devices which are mobile or portable and which performs wirelesscommunications. Examples of UE devices include mobile telephones orsmart phones (e.g., iPhone™, Android™-based phones), portable gamingdevices (e.g., Nintendo DS™ PlayStation Portable™, Gameboy Advance™,iPhone™), laptops, wearable devices (e.g. smart watch, smart glasses),PDAs, portable Internet devices, music players, data storage devices, orother handheld devices, etc. In general, the term “UE” or “UE device”can be broadly defined to encompass any electronic, computing, and/ortelecommunications device (or combination of devices) which is easilytransported by a user and capable of wireless communication.

Base Station—The term “Base Station” has the full breadth of itsordinary meaning, and at least includes a wireless communication stationinstalled at a fixed location and used to communicate as part of awireless telephone system or radio system.

Processing Element—refers to various elements or combinations ofelements that are capable of performing a function in a device, such asa user equipment or a cellular network device. Processing elements mayinclude, for example: processors and associated memory, portions orcircuits of individual processor cores, entire processor cores,processor arrays, circuits such as an ASIC (Application SpecificIntegrated Circuit), programmable hardware elements such as a fieldprogrammable gate array (FPGA), as well any of various combinations ofthe above.

Channel—a medium used to convey information from a sender (transmitter)to a receiver. It should be noted that since characteristics of the term“channel” may differ according to different wireless protocols, the term“channel” as used herein may be considered as being used in a mannerthat is consistent with the standard of the type of device withreference to which the term is used. In some standards, channel widthsmay be variable (e.g., depending on device capability, band conditions,etc.). For example, LTE may support scalable channel bandwidths from 1.4MHz to 20 MHz. In contrast, WLAN channels may be 22 MHz wide whileBluetooth channels may be 1 Mhz wide. Other protocols and standards mayinclude different definitions of channels. Furthermore, some standardsmay define and use multiple types of channels, e.g., different channelsfor uplink or downlink and/or different channels for different uses suchas data, control information, etc.

Band—The term “band” has the full breadth of its ordinary meaning, andat least includes a section of spectrum (e.g., radio frequency spectrum)in which channels are used or set aside for the same purpose.

Automatically—refers to an action or operation performed by a computersystem (e.g., software executed by the computer system) or device (e.g.,circuitry, programmable hardware elements, ASICs, etc.), without userinput directly specifying or performing the action or operation. Thusthe term “automatically” is in contrast to an operation being manuallyperformed or specified by the user, where the user provides input todirectly perform the operation. An automatic procedure may be initiatedby input provided by the user, but the subsequent actions that areperformed “automatically” are not specified by the user, i.e., are notperformed “manually”, where the user specifies each action to perform.For example, a user filling out an electronic form by selecting eachfield and providing input specifying information (e.g., by typinginformation, selecting check boxes, radio selections, etc.) is fillingout the form manually, even though the computer system must update theform in response to the user actions. The form may be automaticallyfilled out by the computer system where the computer system (e.g.,software executing on the computer system) analyzes the fields of theform and fills in the form without any user input specifying the answersto the fields. As indicated above, the user may invoke the automaticfilling of the form, but is not involved in the actual filling of theform (e.g., the user is not manually specifying answers to fields butrather they are being automatically completed). The presentspecification provides various examples of operations beingautomatically performed in response to actions the user has taken.

Approximately—refers to a value that is almost correct or exact. Forexample, approximately may refer to a value that is within 1 to 10percent of the exact (or desired) value. It should be noted, however,that the actual threshold value (or tolerance) may be applicationdependent. For example, in some embodiments, “approximately” may meanwithin 0.1% of some specified or desired value, while in various otherembodiments, the threshold may be, for example, 2%, 3%, 5%, and soforth, as desired or as required by the particular application.

Concurrent—refers to parallel execution or performance, where tasks,processes, or programs are performed in an at least partiallyoverlapping manner. For example, concurrency may be implemented using“strong” or strict parallelism, where tasks are performed (at leastpartially) in parallel on respective computational elements, or using“weak parallelism”, where the tasks are performed in an interleavedmanner, e.g., by time multiplexing of execution threads.

Various components may be described as “configured to” perform a task ortasks. In such contexts, “configured to” is a broad recitation generallymeaning “having structure that” performs the task or tasks duringoperation. As such, the component can be configured to perform the taskeven when the component is not currently performing that task (e.g., aset of electrical conductors may be configured to electrically connect amodule to another module, even when the two modules are not connected).In some contexts, “configured to” may be a broad recitation of structuregenerally meaning “having circuitry that” performs the task or tasksduring operation. As such, the component can be configured to performthe task even when the component is not currently on. In general, thecircuitry that forms the structure corresponding to “configured to” mayinclude hardware circuits.

Various components may be described as performing a task or tasks, forconvenience in the description. Such descriptions should be interpretedas including the phrase “configured to.” Reciting a component that isconfigured to perform one or more tasks is expressly intended not toinvoke 35 U.S.C. § 112(f) interpretation for that component.

FIGS. 1 and 2—Communication System

FIG. 1 illustrates a simplified example wireless communication system,according to some embodiments. It is noted that the system of FIG. 1 ismerely one example of a possible system, and that features of thisdisclosure may be implemented in any of various systems, as desired.

As shown, the example wireless communication system includes a basestation 102A which communicates over a transmission medium with one ormore user devices 106A, 106B, etc., through 106N. Each of the userdevices may be referred to herein as a “user equipment” (UE). Thus, theuser devices 106 are referred to as UEs or UE devices.

The base station (BS) 102A may be a base transceiver station (BTS) orcell site (a “cellular base station”), and may include hardware thatenables wireless communication with the UEs 106A through 106N.

The communication area (or coverage area) of the base station may bereferred to as a “cell.” The base station 102A and the UEs 106 may beconfigured to communicate over the transmission medium using any ofvarious radio access technologies (RATs), also referred to as wirelesscommunication technologies, or telecommunication standards, such as GSM,UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces),LTE, LTE-Advanced (LTE-A), 5G new radio (5G NR), HSPA, 3GPP2 CDMA2000(e.g., 1×RTT, 1×EV-DO, HRPD, eHRPD), etc. Note that if the base station102A is implemented in the context of LTE, it may alternately bereferred to as an ‘eNodeB’ or ‘eNB’. Note that if the base station 102Ais implemented in the context of 5G NR, it may alternately be referredto as ‘gNodeB’ or ‘gNB’.

As shown, the base station 102A may also be equipped to communicate witha network 100 (e.g., a core network of a cellular service provider, atelecommunication network such as a public switched telephone network(PSTN), and/or the Internet, among various possibilities). Thus, thebase station 102A may facilitate communication between the user devicesand/or between the user devices and the network 100. In particular, thecellular base station 102A may provide UEs 106 with varioustelecommunication capabilities, such as voice, SMS and/or data services.

Base station 102A and other similar base stations (such as base stations102B . . . 102N) operating according to the same or a different cellularcommunication standard may thus be provided as a network of cells, whichmay provide continuous or nearly continuous overlapping service to UEs106A-N and similar devices over a geographic area via one or morecellular communication standards.

Thus, while base station 102A may act as a “serving cell” for UEs 106A-Nas illustrated in FIG. 1, each UE 106 may also be capable of receivingsignals from (and possibly within communication range of) one or moreother cells (which might be provided by base stations 102B-N and/or anyother base stations), which may be referred to as “neighboring cells”.Such cells may also be capable of facilitating communication betweenuser devices and/or between user devices and the network 100. Such cellsmay include “macro” cells, “micro” cells, “pico” cells, and/or cellswhich provide any of various other granularities of service area size.For example, base stations 102A-B illustrated in FIG. 1 might be macrocells, while base station 102N might be a micro cell. Otherconfigurations are also possible.

In some embodiments, base station 102A may be a next generation basestation, e.g., a 5G New Radio (5G NR) base station, or “gNB”. In someembodiments, a gNB may be connected to a legacy evolved packet core(EPC) network and/or to a NR core (NRC) network. In addition, a gNB cellmay include one or more transition and reception points (TRPs). Inaddition, a UE capable of operating according to 5G NR may be connectedto one or more TRPs within one or more gNBs.

Note that a UE 106 may be capable of communicating using multiplewireless communication standards. For example, the UE 106 may beconfigured to communicate using a wireless networking (e.g., Wi-Fi)and/or peer-to-peer wireless communication protocol (e.g., Bluetooth,Wi-Fi peer-to-peer, etc.) in addition to at least one cellularcommunication protocol (e.g., GSM, UMTS (associated with, for example,WCDMA or TD-SCDMA air interfaces), LTE, LTE-A, 5G NR, HSPA, 3GPP2CDMA2000 (e.g., 1×RTT, 1×EV-DO, HRPD, eHRPD), etc.). The UE 106 may alsoor alternatively be configured to communicate using one or more globalnavigational satellite systems (GNSS, e.g., GPS or GLONASS), one or moremobile television broadcasting standards (e.g., ATSC-M/H or DVB-H),and/or any other wireless communication protocol, if desired. Othercombinations of wireless communication standards (including more thantwo wireless communication standards) are also possible.

FIG. 2 illustrates user equipment 106 (e.g., one of the devices 106Athrough 106N) in communication with a base station 102, according tosome embodiments. The UE 106 may be a device with cellular communicationcapability such as a mobile phone, a hand-held device, a computer or atablet, or virtually any type of wireless device.

The UE 106 may include a processor that is configured to execute programinstructions stored in memory. The UE 106 may perform any of the methodembodiments described herein by executing such stored instructions.Alternatively, or in addition, the UE 106 may include a programmablehardware element such as an FPGA (field-programmable gate array) that isconfigured to perform any of the method embodiments described herein, orany portion of any of the method embodiments described herein.

The UE 106 may include one or more antennas for communicating using oneor more wireless communication protocols or technologies. In someembodiments, the UE 106 may be configured to communicate using, forexample, CDMA2000 (1×RTT/1×EV-DO/HRPD/eHRPD) or LTE using a singleshared radio and/or GSM or LTE using the single shared radio. The sharedradio may couple to a single antenna, or may couple to multiple antennas(e.g., for MIMO) for performing wireless communications. In general, aradio may include any combination of a baseband processor, analog RFsignal processing circuitry (e.g., including filters, mixers,oscillators, amplifiers, etc.), or digital processing circuitry (e.g.,for digital modulation as well as other digital processing). Similarly,the radio may implement one or more receive and transmit chains usingthe aforementioned hardware. For example, the UE 106 may share one ormore parts of a receive and/or transmit chain between multiple wirelesscommunication technologies, such as those discussed above.

In some embodiments, the UE 106 may include separate transmit and/orreceive chains (e.g., including separate antennas and other radiocomponents) for each wireless communication protocol with which it isconfigured to communicate. As a further possibility, the UE 106 mayinclude one or more radios which are shared between multiple wirelesscommunication protocols, and one or more radios which are usedexclusively by a single wireless communication protocol. For example,the UE 106 might include a shared radio for communicating using eitherof LTE or 5G NR (or LTE or 1×RTT or LTE or GSM), and separate radios forcommunicating using each of Wi-Fi and Bluetooth. Other configurationsare also possible.

FIG. 3—Block Diagram of a UE

FIG. 3 illustrates an example simplified block diagram of acommunication device 106, according to some embodiments. It is notedthat the block diagram of the communication device of FIG. 3 is only oneexample of a possible communication device.

The short to medium range wireless communicationcircuitry 329 and/or cellular communication circuitry 330 may includemultiple receive chains and/or multiple transmit chains for receivingand/or transmitting multiple spatial streams, such as in amultiple-input multiple output (MIMO) configuration.

In some embodiments, as further described below, cellular communicationcircuitry 330 may include dedicated receive chains (including and/orcoupled to, e.g., communicatively; directly or indirectly. dedicatedprocessors and/or radios) for multiple RATs (e.g., a first receive chainfor LTE and a second receive chain for 5G NR). In addition, in someembodiments, cellular communication circuitry 330 may include a singletransmit chain that may be switched between radios dedicated to specificRATs. For example, a first radio may be dedicated to a first RAT, e.g.,LTE, and may be in communication with a dedicated receive chain and atransmit chain shared with an additional radio, e.g., a second radiothat may be dedicated to a second RAT, e.g., 5G NR, and may be incommunication with a dedicated receive chain and the shared transmitchain.

The processor(s) 302 may also be coupled tomemory management unit (MMU) 340, which may be configured to receiveaddresses from the processor(s) 302 and translate those addresses tolocations in memory (e.g., memory 306, read only memory (ROM) 350, NANDflash memory 310) and/or to other circuits or devices, such as thedisplay circuitry 304, short range wireless communication circuitry 229,cellular communication circuitry 330, connector I/F 320, and/or display360. The MMU 340 may be configured to perform memory protection and pagetable translation or set up. In some embodiments, the MMU 340 may beincluded as a portion of the processor(s) 302.

As noted above, the communication device 106 may be configured tocommunicate using wireless and/or wired communication circuitry. Thecommunication device 106 may be configured to perform a method includingperforming one or more of periodic beam quality measurements and/orevent-based beam quality measurements, determining, based at least inpart on one or more of the periodic beam quality measurements and/or theevent-based beam quality measurements, a recommended beam qualitymeasurement configuration, and transmitting, to a base station servingthe UE, the recommended beam quality measurement configuration.

In some cases, the network port 470may couple to a telephone network via the core network, and/or the corenetwork may provide a telephone network (e.g., among other UE devicesserviced by the cellular service provider).

In some embodiments, base station 102 may be a next generation basestation, e.g., a 5G New Radio (5G NR) base station, or “gNB”.

FIG. 5: Block Diagram of Cellular Communication Circuitry

FIG. 5 illustrates an example simplified block diagram of cellularcommunication circuitry, according to some embodiments. It is noted thatthe block diagram of the cellular communication circuitry of FIG. 5 isonly one example of a possible cellular communication circuit. Accordingto embodiments, cellular communication circuitry 330 may be include in acommunication device, such as communication device 106 described above.As noted above, communication device 106 may be a user equipment (UE)device, a mobile device or mobile station, a wireless device or wirelessstation, a desktop computer or computing device, a mobile computingdevice (e.g., a laptop, notebook, or portable computing device), atablet and/or a combination of devices, among other devices.

The cellular communication circuitry 330 may couple (e.g.,communicatively; directly or indirectly) to one or more antennas, suchas antennas 335 a-b and 336 as shown (in FIG. 3). In some embodiments,cellular communication circuitry 330 may include dedicated receivechains (including and/or coupled to, e.g., communicatively; directly orindirectly. dedicated processors and/or radios) for multiple RATs (e.g.,a first receive chain for LTE and a second receive chain for 5G NR). Forexample, as shown in FIG. 5, cellular communication circuitry 330 mayinclude a modem 510 and a modem 520. Modem 510 may be configured forcommunications according to a first RAT, e.g., such as LTE or LTE-A, andmodem 520 may be configured for communications according to a secondRAT, e.g., such as 5G NR.

As shown, modem 510 may include one or more processors 512 and a memory516 in communication with processors 512. Modem 510 may be incommunication with a radio frequency (RF) front end 530. RF front end530 may include circuitry for transmitting and receiving radio signals.For example, RF front end 530 may include receive circuitry (RX) 532 andtransmit circuitry (TX) 534. In some embodiments, receive circuitry 532may be in communication with downlink (DL) front end 550, which mayinclude circuitry for receiving radio signals via antenna 335 a.

Similarly, modem 520 may include one or more processors 522 and a memory526 in communication with processors 522. Modem 520 may be incommunication with an RF front end 540. RF front end 540 may includecircuitry for transmitting and receiving radio signals. For example, RFfront end 540 may include receive circuitry 542 and transmit circuitry544. In some embodiments, receive circuitry 542 may be in communicationwith DL front end 560, which may include circuitry for receiving radiosignals via antenna 335 b.

In some embodiments, a switch 570 may couple transmit circuitry 534 touplink (UL) front end 572. In addition, switch 570 may couple transmitcircuitry 544 to UL front end 572. UL front end 572 may includecircuitry for transmitting radio signals via antenna 336. Thus, whencellular communication circuitry 330 receives instructions to transmitaccording to the first RAT (e.g., as supported via modem 510), switch570 may be switched to a first state that allows modem 510 to transmitsignals according to the first RAT (e.g., via a transmit chain thatincludes transmit circuitry 534 and UL front end 572). Similarly, whencellular communication circuitry 330 receives instructions to transmitaccording to the second RAT (e.g., as supported via modem 520), switch570 may be switched to a second state that allows modem 520 to transmitsignals according to the second RAT (e.g., via a transmit chain thatincludes transmit circuitry 544 and UL front end 572).

In some embodiments, the cellular communication circuitry 330 may beconfigured to perform a method including performing one or more ofperiodic beam quality measurements and/or event-based beam qualitymeasurements, determining, based at least in part on one or more of theperiodic beam quality measurements and/or the event-based beam qualitymeasurements, a recommended beam quality measurement configuration, andtransmitting, to a base station serving the UE, the recommended beamquality measurement configuration. In addition, the UE may performreceiving, from the base station, instructions regarding the beamquality measurement configuration. The instructions may includeinstructions to activate, deactivate, and/or modify at least one beamquality measurement configuration. In addition, the instructions may bebased, at least in part, on the recommended beam quality measurementconfiguration.

As described herein, the modem 510 may include hardware and softwarecomponents for implementing the above features or for time divisionmultiplexing UL data for NSA NR operations, as well as the various othertechniques described herein. The processors 512 may be configured toimplement part or all of the features described herein, e.g., byexecuting program instructions stored on a memory medium (e.g., anon-transitory computer-readable memory medium). Alternatively (or inaddition), processor 512 may be configured as a programmable hardwareelement, such as an FPGA (Field Programmable Gate Array), or as an ASIC(Application Specific Integrated Circuit). Alternatively (or inaddition) the processor 512, in conjunction with one or more of theother components 530, 532, 534, 550, 570, 572, 335 and 336 may beconfigured to implement part or all of the features described herein.

In addition, as described herein, processors 512 may include one or moreprocessing elements. Thus, processors 512 may include one or moreintegrated circuits (ICs) that are configured to perform the functionsof processors 512. In addition, each integrated circuit may includecircuitry (e.g., first circuitry, second circuitry, etc.) configured toperform the functions of processors 512.

As described herein, the modem 520 may include hardware and softwarecomponents for implementing the above features for recommending a beamquality measurement configuration, as well as the various othertechniques described herein. The processors 522 may be configured toimplement part or all of the features described herein, e.g., byexecuting program instructions stored on a memory medium (e.g., anon-transitory computer-readable memory medium). Alternatively (or inaddition), processor 522 may be configured as a programmable hardwareelement, such as an FPGA (Field Programmable Gate Array), or as an ASIC(Application Specific Integrated Circuit). Alternatively (or inaddition) the processor 522, in conjunction with one or more of theother components 540, 542, 544, 550, 570, 572, 335 and 336 may beconfigured to implement part or all of the features described herein.

In addition, as described herein, processors 522 may include one or moreprocessing elements. Thus, processors 522 may include one or moreintegrated circuits (ICs) that are configured to perform the functionsof processors 522. In addition, each integrated circuit may includecircuitry (e.g., first circuitry, second circuitry, etc.) configured toperform the functions of processors 522.

5G NR Architecture with LTE

In some implementations, fifth generation (5G) wireless communicationwill initially be deployed concurrently with current wirelesscommunication standards (e.g., LTE). For example, dual connectivitybetween LTE and 5G new radio (5G NR or NR) has been specified as part ofthe initial deployment of NR. Thus, as illustrated in FIGS. 6A-B,evolved packet core (EPC) network 600 may continue to communicate withcurrent LTE base stations (e.g., eNB 602). In addition, eNB 602 may bein communication with a 5G NR base station (e.g., gNB 604) and may passdata between the EPC network 600 and gNB 604. Thus, EPC network 600 maybe used (or reused) and gNB 604 may serve as extra capacity for UEs,e.g., for providing increased downlink throughput to UEs. In otherwords, LTE may be used for control plane signaling and NR may be usedfor user plane signaling. Thus, LTE may be used to establish connectionsto the network and NR may be used for data services.

FIG. 6B illustrates a proposed protocol stack for eNB 602 and gNB 604.As shown, eNB 602 may include a medium access control (MAC) layer 632that interfaces with radio link control (RLC) layers 622 a-b. RLC layer622 a may also interface with packet data convergence protocol (PDCP)layer 612 a and RLC layer 622 b may interface with PDCP layer 612 b.Similar to dual connectivity as specified in LTE-Advanced Release 12,PDCP layer 612 a may interface via a master cell group (MCG) bearer toEPC network 600 whereas PDCP layer 612 b may interface via a splitbearer with EPC network 600.

Additionally, as shown, gNB 604 may include a MAC layer 634 thatinterfaces with RLC layers 624 a-b. RLC layer 624 a may interface withPDCP layer 622 b of eNB 602 via an X2 interface for information exchangeand/or coordination (e.g., scheduling of a UE) between eNB 602 and gNB604. In addition, RLC layer 624 b may interface with PDCP layer 614.Similar to dual connectivity as specified in LTE-Advanced Release 12,PDCP layer 614 may interface with EPC network 600 via a secondary cellgroup (SCG) bearer. Thus, eNB 602 may be considered a master node (MeNB)while gNB 604 may be considered a secondary node (SgNB). In somescenarios, a UE may be required to maintain a connection to both an MeNBand a SgNB. In such scenarios, the MeNB may be used to maintain a radioresource control (RRC) connection to an EPC while the SgNB may be usedfor capacity (e.g., additional downlink and/or uplink throughput).

Beam Management

In current implementation of the 5G New Radio (5G NR), the beammanagement framework includes a new radio base station (e.g., a “gNB”)transmitting periodic beam management channel state information (CSI) toa user equipment device (“UE”) and the UE measuring and reportingreference signal received power (RSRP) of selected beams. The gNB maymonitor any beam degradation and trigger various beam managementprocedures, e.g., reselection of a beam at the gNB and/or reselection ofa beam at the UE.

For example, FIG. 7 illustrates an example of operation of a beammanagement framework. As shown, a gNB 702 may periodically or routinelytransmit beam management channel state information (CSI) to a userequipment device, such as UE 706. Beam management CSI may includereference signals (RS) such as periodic CSI-RS (P-CSI-RS),semi-persistent CSI-RS (SP-CSI-RS), and/or synchronization signal blocks(SSBs), among other types of reference symbols. The UE 706 maymonitor/measure the RSRP of the beam(s) and may report the RSRP to thegNB 702. The gNB 702 may monitor beam degradation, e.g., based on thereported RSRP and based on detecting beam degradation, the gNB 702 maytrigger beam management procedures, including aperiodic beam managementprocedures (such as P2/P3, discussed below). In some instances, the beammanagement procedures may be triggered if beam management CSI is notsufficient to avoid degradation (e.g., beyond a threshold). Suchaperiodic beam management procedures may be UE-specific, e.g., in orderto avoid the potentially extensive resource cost of doing so for UEsgenerally. As illustrated by FIG. 7, during an exemplary beam managementprocedure, the gNB 702 may transmit a series of beams (e.g., Tx beam) ina sweep (or a series of sweeps), such as TX beam sweep periods 710 a-d,and may transmit RRC configuration information 730 relevant to beammanagement. The UE 706 may detect one or more of the beams, may measurethe strength (e.g., RSRP) or other characteristics of the beam(s), andmay provide one or more reports 735 a-b to the gNB 702 based on thedetection(s) and/or measurement(s).

As a further example, FIGS. 8A-B illustrate respective beam managementprocedures, known as P2 and P3. Turning to FIG. 8A, a beam managementprocedure known as P2 includes a gNB, such as gNB 702, transmitting aseries (e.g., a sweep) of beams 803, e.g., narrow beams at differentangles using a set of CSI resources 814 a-d (CSI resource set or CRS).As shown, a specific CSI resource may correspond to each beam so thateach beam uses a different CSI resource, so that the total group ofbeams uses a specific CRS. For example, a CRS resource set 812 includingfour resources 814 a-d may be used for P2, such that a differentresource is used for each of four beams. In other words, the CRS may notbe repeated, e.g., repetition is off. A receiving UE 706 may use asingle, broad receive (e.g., Rx) beam 804 during the sweep. Based onreports provided by the UE 706, the gNB 702 may select a Tx beam 830.

Turning to FIG. 8B, in contrast to P2, a beam management procedure knownas P3 includes a UE, such as UE 706, performing a sweep of Rx beams 813while the gNB 702 transmits a constant, broad Tx beam 805. The gNB 702may use a single CSI resource set during the sweep 813, e.g., repetitionmay be on. The CRS may include a single resource 824, or multipleresources (e.g., in some instances, the CRS used for P3 may include fiveresources). Based on the measurements (e.g., RSRP) of the Tx beam 805using the different Rx beams, the UE may select an Rx beam 840.

It will be appreciated that other, e.g., not illustrated herein, beammanagement procedures are known, including at least P1, U1, U2, and U3.P1 may include concurrent sweeps of both the gNB (e.g., Tx beam) and UE(e.g., Rx). U1, U2, and U3, may correspond to the P1, P2, and P3procedures, except that the roles may be reversed, e.g., the UE maytransmit a Tx beam and the gNB may receive with an Rx beam.

In addition to general signal degradation requiring beam managementprocedures, motion of a UE may impact beam quality and/or beamselection. FIGS. 9A and 9B illustrate an example of effects of motion ofa UE on beam selection. For example, as illustrated by FIG. 9A, the UE706 and the gNB 702 may use a first pair of Tx and Rx beams 830 and 840,respectively, while the UE 706 is in a first location or orientation.The first pair may result in good channel quality (e.g., high RSRP)given the communication environment. As shown, the selected beams mayavoid certain obstacles and may include reflection from objects toachieve a communicative path. Turning to FIG. 9B, illustrated is aninstance in which the UE 706 may have moved or rotated and, as a result,the first pair of Tx and Rx beams 830 and 840 may no longer result ingood channel quality. The change in the UE 706's position or orientationrelative to the communication environment may lead to degradation of thechannel when using the first pair of Tx and Rx beams 830 and 840. Thus,based on the motion of the UE, selection of a new pair of beams may bedesirable.

Various observations may be appreciated. The behavior of a base station(e.g., eNB or gNB) may be predictable to a UE. For example, a gNB maytransmit SSB and/or CSI on a known (e.g., periodic) schedule. Changes ina desirable beam (e.g., pair of Tx and Rx beams) may result from changesat the UE, such as movement, rotation, or blockage (e.g., a user's handor body, or other surrounding objects), etc. The UE may thus know betterthan a gNB what actions may be taken to mitigate such changes. Forexample, the UE may use radio measurements and/or other sensors (e.g.,accelerometers, GNSS circuitry) to detect changes that may implicateselection of a new beam pair. The gNB, in contrast, may only be able todetect degradation, and not the factors leading to the degradation.Thus, the UE may be better able to determine the cause of degradationand select an appropriate response. However, current as shown, currentbeam management approaches may not support signaling/reporting from a UEto assist beam management procedures (e.g., to initiate P2 vs P3).Accordingly, the gNB 702 may rely on trial and error selection of beammanagement procedures, which may incur costs of power, resources, anddelay. For example, in the case of UE as illustrated in rotation FIGS.9A-B, the gNB 702 may detect RSRP drop (e.g., from a report from the UE706) and may trigger a P2 beam management procedure 801, although P3 mayprovide better likelihood of rapidly selecting an appropriate beam pair.

Thus, as popularity of beam forming in the development of 5G NR hasincreased, UE feedback of beam quality has become of increasinginterest. In particular, periodic beam quality reports from the UE havebeen agreed upon for up to a maximum number of signaled beams. However,for a periodic beam reporting scheme, traffic overhead and linkreliability benefits may need to be balanced, including, for example,adjustment of report periodicity and/or measurement periodicity as wellas perhaps channel state information-reference signal (CSI-RS)periodicity. In addition, for an event-based measurement reportingscheme, which has been shown to effectively maintain good mobilityservice for LTE/UMTS, a faster event report and action may be requiredas compared to LTE/UMTS due to the scale of measurement is smaller forbeams.

Thus, in some embodiments, beam quality measurement reports from a userequipment device (UE), such as UE 106, may include (or be composed of)periodic beam quality reports and/or event-based reports (e.g.,aperiodic beam measurement reports). In some embodiments, for a periodicbeam quality measurement report, the UE may include (or have) acapability to feedback recommended beam quality measurementconfigurations, e.g., report periodicity. In other words, for a periodicbeam quality measurement report, the UE (or a processor of the UE) maybe configured to feedback recommended beam quality measurementconfigurations for beam management. In some embodiments, in response tothe feedback, a base station, such as gNB 102 (and/or gNB 604) (and/orgNB 604), may modify, activate, and/or deactivate one or more beamquality measurement configurations. In other words, the base station maydetermine whether to modify, activate, and/or deactivate beam qualitymeasurement configurations upon reception of UE feedback. In someembodiments, for an event-based beam quality report, the UE mayoptionally recommend certain (or particular) event reports to beactivated. In other words, for an event-based beam quality report, theUE (or a processor of the UE) may be configured to determine whether torecommend particular event beam quality reports to be activated. In someembodiments, the UE may also reserve (or have) an option to recommendbeam management action together with event beam quality report based onexterior information, e.g., from sensors on (or comprised within) theUE. In other words, a modem (or radio, or processor of a radio, e.g.,cellular communication circuitry 330) of the UE may receive informationregarding status of the UE, e.g., movement, rotation, blockage (e.g., ofan antenna or beam) via an object proximate the UE (e.g., a hand or bodyor a user as well as structures). In some embodiments, in response tothe recommendation, a base station, such as gNB 102 (and/or gNB 604),may modify, activate, and/or deactivate one or more beam qualitymeasurement configurations. In other words, the base station maydetermine whether to modify, activate, and/or deactivate beam qualitymeasurement configurations upon reception of the UE recommendation. Inaddition, in some embodiments, the base station may additionally oralternatively provide instructions for UE actions after receiving the UErecommendation.

In some embodiments, for periodic beam measurement configurationfeedback, a preselected candidate set of periodic beam quality reportconfigurations can be setup through radio resource control (RRC)signaling between a UE, such as UE 106, and a base station, such as gNB102 (and/or gNB 604). In some embodiments, a beam quality measurementreference may be based (at last in part) on CSI-RS and/orsynchronization signaling blocks (SSBs). Note that in some embodiments,at most one configuration may be active for each measurement reference(e.g., SSB or CSI-RS). In some embodiments, beam quality report size(e.g., long/middle/short report) and/or beam quality measurementperiodicity can be configured via the RRC signaling between the UE andthe base station. In some embodiments, default configurations may besignaled via the RRC signaling between the UE and the base station.

In some embodiments, the UE (or a radio/baseband processor of the UE,e.g., cellular communication circuitry 330) may be configured to (orhave the capability to) feedback (transmit signaling, e.g., via RRCsignaling, a medium access control (MAC) control element (CE), or ashort subframe of a physical uplink control channel (PUCCH)) recommendedbeam quality measurement configurations to the base station. Forexample, based (at least in part) on information available at the UE(e.g., Doppler shift/spread, motion detection, change/trend of layer 1(L1) RSRP), a periodicity may be selected from a preconfigured set(e.g., as configured via RRC signaling). Additionally, exteriorinformation received at the radio (or baseband processor, e.g., cellularcommunication circuitry 330) of the UE from other sensors of the UE maybe utilized to generate information such as motion/rotation detectionthat the UE may use to determine report periodicity. In someembodiments, the UE may feedback a recommended periodicity for a beamquality measurement reference (e.g., via a MAC CE) instead of (or as analternative to) selecting from a signaled candidate set. In someembodiments, the base station may determine to activate and/ordeactivate periodic beam quality measurement configurations based (atleast in part) on the UE feedback. Note that in some embodiments, a beamquality measurement reference (e.g., CSI-RS and/or SSBs) may only haveone periodic beam quality report configuration active at a given time.In other words, at any time, at most one periodic beam quality reportconfiguration can be active for each beam quality measurement reference(e.g., CSI-RS and/or SSBs).

For example, as illustrated by FIG. 10A, a UE, such as UE 106, maytransmit (on an uplink transmission) periodic beam quality reports forbeam quality measurement references CSI-RS (e.g., reports 1010 a-c) andSSB (e.g., reports 1012 a-b) using periodic beam quality reportconfigurations 1.b and 2.b (e.g., as described by the table of FIG.10B), respectively. In some embodiments, the beam quality reportconfigurations may initially be signaled (e.g., via RRC signaling) froma base station. The UE may then recommend (e.g., via a MAC CE 1020)activating periodic beam quality report configurations 1.a and 2.aand/or recommend setup parameters associated with configurations 1.a and2.a. In response, a base station, such as gNB 102 (and/or gNB 604), maydetermine (e.g., based, at least in part on the recommendation of theUE) to activate periodic beam quality report configurations 1.a and 2.aand deactivate periodic beam quality report configurations 1.b and 2.b,e.g., via a MAC CE 1030 transmitted to the UE on a downlink transmissionand may transmit the indication of the activation and deactivation viathe MAC CE 1030. Upon receiving the MAC CE 1030 from the base station,the UE may then transmit periodic beam quality reports for beam qualitymeasurement references CSI-RS (e.g., reports 1014 a-b) and SSB (e.g.,report 1016 a) using periodic beam quality report configurations 1.a and2.a, respectively.

In some embodiments, for an event-based beam quality report (e.g.,aperiodic beam quality reports), a UE, such as UE 106, may optionallyrecommend certain (or particular) event reports to be activated. Inother words, for an event-based beam quality report, the UE (or aprocessor of the UE) may be configured to determine whether to recommendparticular event beam quality reports to be activated. In someembodiments, a preselected (or preconfigured) candidate set of beamevent beam quality report configurations may be setup (orinitialized/configured) via RRC signaling between the UE and a basestation, such as gNB 102 (and/or gNB 604). For example, a beam qualityreport configuration could be associated with a particular event. Inaddition, the particular event may be characterized by associatedparameters. Thus, in some embodiments, a particular event may beassociated with more than one beam quality report configuration based,at least in part, on the associated parameters. In some embodiments, theassociated parameters may include, but may not be limited to, a triggerthreshold and a time-to-trigger (TTI). In some embodiments, the UE (or aprocessor/radio of the UE, e.g., cellular communication circuitry 330)may be configured to feedback recommended event beam quality reportconfigurations based, at least in part, on exterior information, e.g.,from sensors on (or comprised within) the UE. In other words, a modem(or radio, or processor of a radio, e.g., cellular communicationcircuitry 330) of the UE may receive information regarding status of theUE, e.g., movement, rotation, blockage (e.g., of an antenna or beam) viaan object proximate the UE (e.g., a hand or body or a user as well asstructures) and the UE may base the recommendation on the receivedinformation. In some embodiments, the recommendation may be signaled viaRRC signaling, a MAC CE, and/or a short PUCCH subframe. In someembodiments, in response to the recommendation, the base station maymodify, activate, and/or deactivate one or more beam quality measurementconfigurations based, at least in part, on the recommendation. In otherwords, the base station may determine whether to modify, activate,and/or deactivate beam quality measurement configurations upon receptionof the UE recommendation. Note that in some embodiments, in addition toconsidering the recommendation, the base station may also base thedetermination on other factors, such as channel quality (as measured bythe base station) and/or periodic beam quality reports and/orrecommendations received from the UE. In some embodiments, communicationbetween the base station and UE may implicitly allow for an efficientresponse to UE mobility and/or avoid the UE's own manipulation of eventreport parameters at UE side. In addition, in some embodiments, the basestation may additionally or alternatively provide instructions for UEactions after receiving the UE recommendation. In some embodiments, theUE may include recommended beam management action in the event report,e.g., based, at least in part, on the information regarding status ofthe UE. For example, the UE may recommend beam management actions suchas (but not limited to) UE receiver beam sweep, UE transmitter beamsweep, base station transmitter beam sweep, base station receiver beamsweep, and/or any combination thereof.

For example, as illustrated by FIG. 11A, a UE, such as UE 106, maytransmit (on an uplink transmission) an event report 1110 via RRCsignaling to a base station, such as gNB 102 (and/or gNB 604). The eventreport may optionally include recommended actions. In addition, the UEmay transmit a recommendation 1120 to activate event beam quality reportconfiguration 3 (e.g., as described in FIG. 11B), e.g., via a MAC CE.Note that in some embodiments, there may not be a current (or active)event beam quality report configuration. In addition, note that in someembodiments, the recommendation (or settings related to a configurationand/or a set of parameters related to the configuration) may vary based,at least in part, on a measurement reference (e.g., SSB or CSI-RS). Inresponse, the base station may determine (e.g., based, at least in parton the recommendation of the UE) to activate event beam quality reportconfiguration 3 and may transmit an indication of the activation anddeactivation via a MAC CE 1130. Upon receiving the MAC CE 1130 from thebase station, the UE may then transmit a beam quality report usingconfiguration 3. In addition, the UE may later report (via RRC signaling1140) an occurrence of Event 3 and may optionally include recommendedactions. FIG. 11B further illustrates measurement event configurations1, 2, and 3, among other possible events. For example, event 1 may beassociated with a first TTI (e.g., TTI 1) and a first threshold (e.g.,threshold 1), event 2 may be associated with a second TTI (e.g., TTI 2)and a second threshold (e.g., threshold 2), and event 3 may beassociated with a third TTI (e.g., TTI 3) and a third threshold (e.g.,threshold 3). In addition, events 1 and 2 may be associated with (orhave) an active status and event 3 may be associated with (or have) anon-active status.

FIG. 12 illustrates signaling between a UE, such as UE 106, and a basestation, such as gNB 102 (and/or gNB 604), for both periodic andevent-based (e.g., aperiodic) beam quality reporting, according to someembodiments. As shown, the UE may transmit (on an uplink transmission)periodic beam quality reports for beam quality measurement referencesCSI-RS (e.g., reports 1210 a-c) and SSB (e.g., reports 1212 a-b) usingperiodic beam quality report configurations 1.b and 2.b, respectively.The UE may then recommend (e.g., via a MAC CE 1220) activating periodicbeam quality report configurations 1.a and 2.a. In response, a basestation, such as gNB 102 (and/or gNB 604), may determine (e.g., based,at least in part on the recommendation of the UE) to activate periodicbeam quality report configurations 1.a and 2.a and deactivate periodicbeam quality report configurations 1.b and 2.b, e.g., via a MAC CE 1230transmitted to the UE on a downlink transmission and may transmit theindication of the activation and deactivation via the MAC CE 1230. Uponreceiving the MAC CE 1230 from the base station, the UE may thentransmit periodic beam quality reports for beam quality measurementreferences CSI-RS (e.g., reports 1214 a-b) and SSB (e.g., report 1216 a)using periodic beam quality report configurations 1.a and 2.a,respectively. In addition, the UE may transmit (on an uplinktransmission) an event report 1211 via RRC signaling to the basestation. The event report may optionally include recommended actions.After transmitting the event report 1211, the UE may transmit arecommendation 1220 to activate event beam quality report configuration3, e.g., via a MAC CE. In response, the base station may determine(e.g., based, at least in part on the recommendation of the UE) toactivate event beam quality report configuration 3 and may transmit anindication of the activation and deactivation via a MAC CE 1240.

In some embodiments, beam event transmission may be implemented via aMAC CE and/or via RRC signaling. In some embodiments, events may bespecific to beam quality measurement references (e.g., CSI-RS and/orSSBs). In addition, a trend of L1-RSRP change (e.g., instantaneous,substantially instantaneous, and/or over a specified time period) may beconsidered an event. In some embodiments, events may include: (1) astrongest beam among a group of monitored beam pair links is better than(or exceeds) a threshold; (2) a strongest beam among a group ofmonitored beam pair links is worse than (or below) a threshold; (3) allmonitored beam pair links become weaker than a threshold (may beconsidered a panic event); (4) neighbor beams are better than athreshold (TN) for a time-to-trigger (TTT) time where TN may bedifferent between configured neighbor beam measurements based on CSI-RSand general beam measurements based on SSB and TTT may be different fordifferent beam categories; (5) serving beam is worse than a firstthreshold (TH1) and a neighbor beam exceeds a second threshold (TH2) fora time hysteresis TTT (e.g., best beam switch, as discussed in moredetail below); (6) serving beam quality continuously (or substantiallycontinuously) reduces in last N1 configured measurement cycles withstepsize more than T1 and neighbor beam quality continuously (orsubstantially continuously) increases in the last N2 configuredmeasurement cycles with stepsize more than T2 (e.g., bean quality changewith trend detection, as discussed in more detail below); and/or (7)un-symmetric (e.g., not reciprocal) UL and DL beams (e.g., based on ULquality as observed at the UE, may include sounding reference failure,random access failure, a negative acknowledgment on a physical uplinkshared channel (PUSCH), and/or real-time transport protocol loss on UL).

For example, in some embodiments, an event may include a best beamswitch in which a serving beam is worse than a first threshold (TH1) anda neighbor beam exceeds a second threshold (TH2) for a time hysteresisTTT. In some embodiments, neighbor beams may include beams configured bya base station, such as gNB 102, for a UE, such as UE 106, to monitor onCSI-RS. In some embodiments, neighbor beams may (also) include beamsfrom SSB measurement which may not be mandatory for the UE to measure.In some embodiments, TH2 and TTT may be different for beams configuredby the base station for the UE to monitor on CSI-RS and for beams basedon SSB measurement. Note that, in general, TH2 may be higher and TTTlonger for beams based on SSB measurement as compared to beams based onCSI-RS measurement.

As another example, an event may include a beam quality change withtrend detection in which a serving beam quality continuously (orsubstantially continuously) reduces in last N1 configured measurementcycles with stepsize more than T1 and neighbor beam quality continuously(or substantially continuously) increases in the last N2 configuredmeasurement cycles with stepsize more than T2. Note that in someembodiments, T1 and T2 may be the same (or different) and similarly, N1and N2 may be the same (or different). In some embodiments, the eventmay be considered multiple events, e.g., a first event may be theservice beam reducing and a second event may be a neighbor beamimproving. In some embodiments, the purpose of the trend detection maybe to trigger early beam handover, thus N1 time measurement periodicitymay be substantially less than the TTT in the best beam switch eventdescribed above. Note that the event may be combined with the best beamevent with separate beam quality measurement configurations, in someembodiments.

For example, FIG. 13 illustrates beam event detections, according tosome embodiments. As shown, a current beam 1304 may be rapidly degradingat a first point in time and slowly degrading at second point in time.Further, a neighbor beam 1302 may be rapidly improving at the firstpoint in time and slowly improving at the second point in time. Thus, atthe second point in time, a best beam switch event 1320 may aid indetection and resolution of a slow beam change with large variation,e.g., as illustrated by the differences in beam quality of beams 1302and 1304. Note that in such an event, a time to trigger may delay theswitch form beam 1304 to 1302 for a period of time after the beam 1302has exceeded threshold TH2 and beam 1304 has dropped below thresholdTH1. However, the best beam switch event 1320 may not be ideal for rapidbeam change with smaller variation. Thus, a beam quality change withtrend detection event 1310 may aid in detection and resolution of a fastbeam change with lower variation, e.g., due to UE mobility. Note that insuch an event, rapid degradation (e.g., greater than T1) in beam qualityof beam 1304 may be detected at multiple points in time and maycorrespond to rapid increase (e.g., greater than T2) in beam quality ofbeam 1302 at the same points in time, thereby triggering event 1310.

FIG. 14 illustrates a block diagram of an example of a method for beamquality management, according to some embodiments. The method shown inFIG. 14 may be used in conjunction with any of the systems or devicesshown in the above Figures, among other devices. In various embodiments,some of the method elements shown may be performed concurrently, in adifferent order than shown, or may be omitted. Additional methodelements may also be performed as desired. As shown, this method mayoperate as follows.

At 1402, a user equipment device, such as UE 106 (or circuitry of a UE,such as cellular communication circuitry 330), may perform beam qualitymeasurements. The beam quality measurements may be performed accordingto one or more beam quality measurement configurations. In someembodiments, the beam quality measurements may use (or be performed withrespect to) one or more reference signals (RSs) received from a basestation, such as gNB 102/604, serving the UE. The reference signals maybe based, at least in part, on a channel state information (CSI) (e.g.,the reference signals may include periodic CSI-RS (P-CSI-RS) and/orsemi-persistent CSI-RS (SP-CSI-RS)) and/or synchronization signal blocks(SSBs), among other types of reference symbols. In some embodiments, thebeam quality measurements may be performed periodically and/or may beperformed responsive to an event (e.g., aperiodically). In other words,the UE may periodically perform beam quality measurements and/or the UEmay perform event-based beam quality measurements. In some embodiments,an event triggering performance of event-based beam quality measurementsmay include any of a detection (by the UE or circuitry of the UE) of astrongest beam among a group of monitored beam pair links exceeding athreshold, a detection (by the UE or circuitry of the UE) of a strongestbeam among a group of monitored beam pair links is dropping below athreshold, a detection (by the UE or circuitry of the UE) of allmonitored beam pair links becoming weaker than a threshold, a detection(by the UE or circuitry of the UE) of neighbor beams that are betterthan a threshold (TN) for TTT time, a detection (by the UE or circuitryof the UE) of a serving beam being worse than a first threshold (TH1)and a neighbor beam exceeding a second threshold (TH2) for a timehysteresis TTT, a detection (by the UE or circuitry of the UE) of aserving beam quality continuously (or substantially continuously)reducing in last N1 configured measurement cycles with stepsize morethan T1 and neighbor beam quality continuously (or substantiallycontinuously) increasing in the last N2 configured measurement cycleswith stepsize more than T2, and/or a detection (by the UE or circuitryof the UE) of un-symmetric (e.g., not reciprocal) UL and DL beams basedon UL quality as observed at the UE.

At 1404, the UE (or circuitry of the UE) may determine, based at leastin part on the beam quality measurements, a recommended beam qualitymeasurement configuration. In some embodiments, the recommended beamquality measurement configuration may be further based (or alternativelybased), at least in part, on conditions at the UE. In other words, therecommended beam quality measurement configuration may be based, atleast in part, on environmental conditions measured by (or at) the UE(and/or fed back to circuitry of the UE, e.g., via motion sensorsincluded on the UE). For example, conditions relevant to beam qualitymanagement may include any of a detected Doppler shift, a change inDoppler spread, motion detection, rotation detection, change of layer 1reference signal received power (L1-RSRP), a trend in the change ofL1-RSRP, and/or detection of blockage of at least one antenna of the UE.In some embodiments, recommended beam quality measurement configurationmay include one of a periodic measurement configuration index and/or aset of measurement parameters associated with the recommended beamquality measurement configuration.

At 1406, the UE (or circuitry of the UE) may transmit, to the basestation serving the UE, the recommended beam quality measurementconfiguration. In some embodiments, the UE may transmit the recommendedbeam quality measurement configuration via a medium access control (MAC)control element (CE). In some embodiments, the UE may transmit therecommended beam quality measurement configuration via a radio resourcecontrol (RRC) message. In some embodiments, the UE may transmit therecommended beam quality measurement configuration via a short format(e.g., according to 5G NR RAT) physical uplink control channel (PUCCH)frame or subframe.

At 1408, the UE may receive, from the base station, instructionsregarding the beam quality measurement configuration. In someembodiments, the instructions regarding beam quality measurementconfiguration, may be based, at least in part, on the recommendationreceived from the UE. In some embodiments, the instructions may includeactivation of at least one beam quality measurement configuration,deactivation of at least one beam quality measurement configuration,and/or modification of at least one beam quality measurementconfiguration.
